I came here several months ago but passed it recently in my travels and distinctly remembered the wonderful service provided. I came to this McDonald’s late at night on a drive to Iowa and I think it may have been the manager who was alone working? He cooked up the freshest quarter pounder I’ve ever had at a McDonald’s. We had a nice chat, he talked through how many minutes or seconds each part of the cooking process is supposed to take, and shared the insight that oftentimes one might get fresher food at McDonald’s at night time because they don’t leave food sitting and cook things to order. A pleasant experience with a kind person. If I ever stop at the oasis, I’ll probably stop by.

I can’t think about it anymore because I had threw up twice already after a bite. This is the double quarter cheese burger I ordered. The bun was soaked wet in weird taste, horrible looking just see the box, it’s even wet everywhere inside the box. I just can not believe McDonald Dekalb oasis location made the brand name down to the hill. the fries was hard and chewy, but this double cheeseburger is really out of my imagination that what the chef did to soaked the buns???!!! Insane! Please watch out if you order from the McDonald from Dekalb oasis!

Slower than time itself. In fact, the only thing you’ll be spending here is your precious time, because you’ll be in line for two weeks before you get your food. You could read the Bible faster than you’ll receive your order. Leave your money in your pocket - your food will never come.

Was craving something sweet. Came in late at night after a long day of driving. Pleasantly surprised this place was open and the Mcflury machines were working.

We stopped by this McDonald’s on our way back to Iowa! It was fairly late, Regardless of this, Matthew did a wonderful job of getting us our food out in a timely manner! The fries were fresh and so were our nuggets. The service was great, despite the late hour, Matthew was friendly and welcoming.
